How can we increase the efficiency of the boiler in

2019-10-23 · Decreasing the condenser pressure: The overall effect of lowering the condenser pressure is an increase in the cycle's thermal efficiency. It should be mentioned that it is possible to increase the average temperature at which heat is added to the steam without increasing the pressure of the boiler.

Boiler (Steam Generator) - Coal Fired Power Plant

2019-10-28 · A boiler or Steam Generator (prime mover) is an integral device in a fossil fuel power plant used to produce steam by applying heat energy to water. A boiler incorporates a furnace in order to burn the fossil fuel (coal, gas, waste etc.) and generate heat which is transferred to water to make steam.

What is the function of economizer in boiler? …

A common application of economizers in steam power plants is to capture the waste heat from boiler stack gases (flue gas) and transfer it to the boiler feedwater. This raises the temperature of the boiler feedwater, lowering the needed energy input, in turn reducing the firing rates needed for the rated boiler …

Boiler Water Treatment - Why is It Important

Boiler water quality is of prime concern to all boiler operators. The process of water treatment in boilers is not limited to producing high quality DM water. The stringent water chemistry requirements of Supercritical power plants makes water treatment in boilers a very critical aspect of power plant operation. This necessitates the use of a high quality water treatment system.
